Wait-to-Start Light
For diesel engines, the wait-to-start
light shows that the engine is
functioning properly and indicates
when the engine can be started.
The fast warm-up glow plug system
makes the wait-to-start light stay on
for a shorter amount of time than
most diesel engines.
For more information, see Starting
the Engine 0209.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.

200 Driving and Operating
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0298.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering assist. Always
have the engine running and the
vehicle in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills;
something could be in your lane
(e.g., stalled car, accident).
. Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.

Use the recommended engine oil
when the outside temperature drops
below freezing. SeeEngine Oil
0 265. When the outside
temperature drops below –18°C
(0°F), use of the engine heater is
recommended.
See Fuel for Diesel Engines 0246
for information on what fuel to use in
cold weather.
If the Diesel Engine Will Not
Start
If you have run out of fuel, see
Running Out of Fuel (Diesel) 0253.
If the vehicle is not out of fuel, and
the engine will not start, do this:
Turn the ignition on. Immediately
after the wait-to-start light goes off,
press ENGINE START/STOP.
If the light does not go off, wait a
few seconds, then try starting the
engine again. See your dealer for a
starting system check.
If the light comes on and then goes
off, and it is known that the batteries
are charged, but the engine still will
not start, the vehicle needs service. If the light does not come on when
the engine is cold, the vehicle
needs service.
If the batteries do not have enough
charge to start the engine, see
Battery - North America
0279.
Check that the correct engine oil
has been used and changed at
appropriate intervals. If the wrong oil
is used, the engine may be harder
to start.
Be sure you are using the proper
fuel for existing weather conditions.
See Fuel for Diesel Engines 0246.
If the engine starts, runs a short
time, then stops, the vehicle needs
service.
{Warning
Do not use gasoline or starting
aids, such as ether, in the air
intake. They could damage the
engine, which may not be
covered by the vehicle warranty.
They could also cause a fire,
which could cause serious
personal injury.
Engine Heater
If equipped, the gasoline engine
block heater and diesel engine oil
pan heater can help in cold weather
conditions at or below −18 °C (0 °F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the heater at least four hours
before starting the vehicle.
A thermostat that is part of the block
heater cord will prevent engine
block heater operation at
temperatures above −18 °C (0 °F).
{Warning
Do not plug in the engine block
heater while the vehicle is parked
in a garage or under a carport.
Property damage or personal
injury may result. Always park the
vehicle in a clear open area away
from buildings or structures.

214 Driving and Operating
To Use the Heater
1. Turn off the engine.
2. Open the hood and unwrap theelectrical cord. For gasoline
engines, the electrical cord is
on the passenger side of the
engine compartment between
the headlamp and the air
cleaner. For diesel engines, the
electrical cord is on the driver
side of the engine compartment
near the fuse box.
3. Check the heater cord for damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
4. Plug it into a normal, grounded 110-volt AC outlet.
5. Before starting the engine, be sure to unplug and store the
cord as it was before to keep it
away from moving engine
parts. If you do not it could be
damaged.{Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
. Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection
function. An ungrounded
outlet could cause an
electric shock.
. Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension
cord in good operating
condition, or using a
damaged heater or
extension cord, could make
it overheat and cause a fire,
property damage, electric
shock, and injury.
(Continued)
Warning (Continued)
.Do not operate the vehicle
with the heater cord
permanently attached to the
vehicle. Possible heater
cord and thermostat
damage could occur.
. While in use, do not let the
heater cord touch vehicle
parts or sharp edges. Never
close the hood on the
heater cord.
. Before starting the vehicle,
unplug the cord, reattach
the cover to the plug, and
securely fasten the cord.
Keep the cord away from
any moving parts.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.

Shifting Into Park
(Automatic Transmission)
1. Hold the brake pedal down andset the parking brake.
See Parking Brake 0229.
2. Hold the button on the shift lever and push the lever toward
the front of the vehicle into
P (Park).
3. Turn off the ignition.
Leaving the Vehicle with the
Engine Running
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park (Automatic
Transmission) 0215.
If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking
brake set. Release the button and check that
the shift lever cannot be moved out
of P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not
done properly and then it is difficult
to shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see
“Shifting Into Park”
listed previously.
If torque lock does occur, the
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).
Shifting out of Park
(Automatic Transmission)
This vehicle is equipped with an
automatic transmission shift lock
control system. The shift lock is
designed to:

Diesel Particulate
Filter
The Diesel Particulate Filter (DPF)
filters soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
and may take up to 20 minutes.
Fuel consumption may be higher
during this period.
Under certain driving conditions,
e.g. short distances, the system
cannot clean itself automatically.
If the cleaning of the filter is required
and if previous driving conditions did
not enable automatic cleaning, a
warning message appears in the
DIC. Start the cleaning process as
soon as possible. Cleaning Process
To activate the cleaning process,
continue driving safely, and keep
vehicle speed above 41 km/h (25
mph) until the warning message in
the DIC goes off.
If the vehicle continues to be driven
with the DPF warning message on,
and the exhaust filter is not cleaned
as required, the malfunction
indicator lamp and the ENGINE
POWER IS REDUCED message
will come on and dealer service is
necessary. See
Malfunction
Indicator Lamp (Check Engine
Light) 0130.
{Warning
During DPF self cleaning or
during extended idling while
parked, the exhaust system and
exhaust gases are very hot.
Things that burn could touch hot
exhaust parts under the vehicle
and ignite. You or others could be
burned. Do not park, or idle for an
extended period of time, near or

To stop, let up on the accelerator
pedal and press the brake pedal.
Just before the vehicle stops, press
the clutch pedal and the brake
pedal, and shift to Neutral.
Neutral :Use this position when
you start or idle the engine. The
shift lever is in Neutral when it is
centered in the shift pattern, not in
any gear.
R : To back up, with the vehicle at a
complete stop, press down the
clutch pedal. Then fully press the
reverse button on the front side of
the shift lever and then shift into
R (Reverse). Let up on the clutch
pedal slowly while pressing the
accelerator pedal. If the gear does not engage, shift
the transmission to Neutral, release
the clutch pedal, and press it back
down. Repeat the gear selection.{Warning
If you skip a gear when
downshifting, you could lose
control of the vehicle. You could
injure yourself or others. Do not
shift down more than one gear at
a time when downshifting.
Caution
Do not skip gears while
upshifting. This can cause
premature wear in the
transmission. The repairs would
not be covered by the vehicle
warranty.
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
may be heard while this test is going
on, and it may even be noticed that
the brake pedal moves a little. This
is normal.
If there is a problem with ABS, this
warning light stays on. See
Antilock
Brake System (ABS) Warning Light
0 132.

Driving and Operating 231
Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See
If the Vehicle Is Stuck 0202
and “Turning the Systems Off and
On” later in this section.
